Seal Performance: After the closures are sealed, then pressurized up to 100KPa±5KPa in water, immersed in 15 minutes, there are no air bubbles; Or observed for 24 hours, there is no change of air pressure.

Re-encapsulation Performance: The closures are pressurized up to 100KPa±5KPa in water, immersed in 15 minutes, there are no air bubbles; Or observed for 24 hours, there is no change of air pressure after three times of repeat encapsulation.

Voltage-resistance strength: Under the effect of 15kv/DC/1min, non-puncture, and no arc-over.

It is widely used for communication, network system, cabled T.V. of CATV, the fiber optic cable by network

Uses and properties:
It is belonged to open structure airproof tie-in system of machine pressure.
It is used for the protective connection between two or more optical cables.
Suitable for single core fiber optic cable and ribbon fiber optic cable.
